NOTE: FRI is stored in the FRI directory, /var/opt/fse/fri/, after recreating FRI for closed WORM volumes.

The existing FRI on the medium volume and system volume will be overwritten with the newly created FRI. If there is not enough space on the medium volumes, the FRI is stored to the FRI directory on disk. The FRI directory path is /var/opt/fse/fri (on Linux systems) or %InstallPath%\var\fri (on Windows systems).

Inconsistent or incomplete FRI can be detected with the FSC vs. media check. For more information, see ”Consistency check of FSC vs. FSE media” on page 182.

To recreate FRI, use the following command:

fsemedium --recreate-fri Barcode [--volume VolumeNumber]

NOTE: Recreating FRI on single-volume media such as LTO 1, LTO 2, and LTO 3 can take a considerable amount of time.

Removing FSE media

You can only remove a medium from the FSE implementation if the medium has not yet been used (initialized), or the respective FSE partition was removed from the FSE implementation and the medium is not assigned to the partition (the medium has its status set to free). Before removing a medium, you need to make sure that all FSE medium volumes on it are empty:

fsemedium --remove Barcode

NOTE: When you remove an FSE medium using fsemedium --remove, it is also logically removed from the FSE library in which it is located. This means that the medium is no longer reported in the output of the fselibrary --listcommand.

If the medium is still physically present in the library, trigger a library inventory update to include the medium barcode again in the logical inventory of the library. Use the

fselibrary --update-inventory command for this purpose.

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
